vented or unvented - van disks

i know the real answer is ill have to wait and check but im very far from my van and book of lies right now.

looking on carparts4less at pagid disks for my peugeot partner 1.9D - current ones are warped after summer in the alps.

Im fairly sure they are solids on atm (factory fits) - but my van throws up two replacement part numbers for the disks - one is vented and one is solid - vented is a 10er cheaper

is it as simple and throwing on a pair of vented disks (which are 22mm thick as oppose to 13mm thick) and adjusting the calpers/pistons accordingly or was it a factory fit upgrade on the brakes/calipers ? - in which case ill just pay my 10 pounds and get solids

lets face it they probably just warped because of age/wear- they have done 77k miles.

just thought it strange that my reg throws up both types as a replacement. - i need new pads as well anyway - but i aint going to the expense of calipers for the once a year excursion to big hills and high temperatures.....

Are they not showing the part numbers for front and rear? I'd imagine that the fronts will be vented as not many cars of any size these days not running vented disks up front - even small cars run vented disks up front and solids on the rear.

I've replaced the brakes on a car where someone had fitted solid discs when it should have had vented.

Friend had driven over to London and said the brakes were making funny noises. Got him to send me a photo and the discs looked badly scored. When he got back I discovered the full extent of the problem and one of the pads had lost all it's braking surface and another on the other side had lost half of it. Presumably because the pads were ending up at a funny angle. At least the piston didn't pop out or that would have been very messy!

well my van is at 187k on the original disks (unvented, 90s sprinter).....if you doing long long descents ie the alps, that is where vented disks come in. they are warped because they got too hot, not from age/distance.
what van is it?
i know i can change to vented on the same callipers on my van, didnt bother as a tend to brake-cool-brake-cool kinda thing if im going down long hills fully laden

try some of the standard quality ones from GSF good price and should work realy well. I work for them have them all round on my own car and sell a boat load of them to local taxi firms with no complaints and they get a seriously hard life with some of these boys behind the wheel
